the identical type and compatible series Module. Perform the following steps to
replace the I/O Module:
WARNING: Contact with AC line potentials may cause injury to
personnel. Removing power from the System Power Supply does
not remove the external power source supplying the Field Wiring
Arm. Failure to remove this external power source causes voltage to
be present at the Field Wiring Arm terminals.
1.
Place the Mini–PLC–2/15 Processor in the PROG mode.
2.
Support Processor memory if necessary.
3.
Remove system power and I/O power.

Remove the I/O Module and install the replacement Module. Be sure it is
the same type and series level as the one removed.
